OtherInfo	Mallet devised methods for the determination of organic matter in portable water and characterised meteorites and rare terrestrial minerals; particularly, the occurrence of silver in the ash of South America volcanoes. He accurately determined the density of solid mercury, molecular weight of hydrofluoric acid and the atomic weights of lithium (1856), aluminium (1880) and gold. Mallet also served as expert witness in many court cases involving poisoning, value of iron ore, pollution of river water and other chemical questions.
